Abstract
The crosslinking of an ethylene–;tetrafluoroethylene copolymer by exposure to an argon plasma, excited by an inductively coupled RF field, is studied over a wide range of pressures and power loadings. The results are interpreted in terms of a two‐component, direct and radiative energy‐transfer model showing that the outermost monolayer crosslinks rapidly via direct energy transfer from argon ions and metastables.
